To all whom it may concern." v

Be it known that I, EDWARD H. Govn, a citizen of the United States, residing at Biddeford, in the county ofYork and btate of Maine, have invented certain new and useful Improvements in Tank-Siphons of which the following is-a specification.

. This invention relates to improvements in tank siphons. It is designed to produce a device which will operate with absolute certainty and with the greatest ease. It is also designed; to deliver a fixed quantity of liquid at each operation of the siphon. It is also designed to produce a device which is simple and inexpensive in construction.

In the drawing herewith accompanying and making a part of this application I have shown one embodiment of my invention, but the siphon action producing mechanism may be applied to any form of siphon. In said drawings Figure 1 is aperspective view of one form of siphon and its operating mechanism, a portion of the short leg and tank being broken away; Fig. 2 is' a detail sectional View of the mechanism which prevents the siphon action recurring before the initial action is complete; Fig. 3 is a sectional view showing the apparatus constructed for use in tanks of less depth or where the lifting rod passes flirough the short leg; Fig. 4 isavertical sectional view where the lifting rod passes through the side of the short leg, and 5 is a vertical detail plan view of a portion of the same. I,

Same reference characters indicate like parts in the several figures. j

In said drawings 1 represents a liquid tank of any usual construction in which is mounted a long leg 2 flaring at the top as seen at 3 and provided with openings 4; in the top formed by the removal of a portion of the top and sides. The leg 2 has cast thereon projections 5 which serve to give lateral support to a shortleg 6, which short leg may be of any suitable material, preferably of glass. of the flaring top of leg 2 is a groove 7 and in the projections 5 are grooves 8 in vertical line with groove 7. The leg 6 has an interior vertical tongue 9 on each side adapted to take into said grooves in the long leg when the short leg is placed down over the end thereof, thus holding it firmly against any movement relative thereto except up and down movement. Siphon movement is In each of opposite sides Specification of Letters Patent. 7 Patented Sept. 21,;1926.

produced means of plunger comprising V adjacent said long leg. The plates 10 have ears 10 in the top by which they are pivotally mounted on a pivot 11 in arms-12of a carrying frame which comprises a ring .13 and a ring 14 spaced apart downwardly therefrom and -united by links 15, which frame and links-may be cast in one piece if desired. It is movable up and down relative to and upon leg 2 and maybe raised by a chain 16 attached to the lower ringf The plates are pivotally-mountedso; that gravity willcause them to return downa's soon'as the siphon action ceases. The plates of the plunger preferably have slightly up-. turned flanges 17 on the outer edges which preferably flare outwardly somewhat to ease the movement of the plunger and to better hold the liquid. 1

' The operation of this form of my afppae ratus is as follows:

To start the siphon action the plunger is raised bodily upwardly in leg 6 lifting the liquidtherein until it overflows into leg 2 through openings 4. As soon as the siphon action is started the operating lever may be released and the weight ofthe plunger will cause it to return down, the plates ofthe plunger being free to turn, upwardly'hon their. pivotspffering substantially no obstruction to the down return, theplates, as. suming, when down and siphon action has ceased, automatically a horizontal position.

It will be understood that the rising liquid in thetank will turn the plunger plates automatically on their pivots to admit liquid into leg 6 to the depth of liquid in the tank.

It sometimes happens that when the inlet to the tank is rapid the inflowing liquid refills the tank above the siphon intake before the siphon action is completed and a supplemental siphoning takes place. this unnecessary waste of liquid I secure to the top of leg 6 a cap 18 open into the siphon chamber and mounted in said cap is a pipe 19 whichextends downwardly to about'the same position as the plunger plates and thence turns upwardly as seen at 20 so that the siphon action will continue until the To prevent V liquid in the tank is reduced to the level of the plunger plates and cannot be restored until the liquid in the tank rises again above the end 20 of the pipe on account of the breaking of the siphonaction by admission of air.

. In Figs 3, 4 and 5 I have shown fica'tion of my invention adapted for use in tanks in which the liquid is usually of less depth, Here the carrying frame has only one ring and the plunger is lifted by a rod 21 extendingup the inside of the'short leg,

. offset 24 extending to a point midway of the leg and has an opening 25 at the top. In this case the lifting rod runs in said offset and through said opening. It is provided with a cap 23' and operates as the rod and cap does in Fig. 3. The liquid in the short leg will remain under pressure until the liquid in the tank falls below the end ofthe tube in the one case or the upper end of the offset inthe other case. Before this occurs the plunger being released will fall to its seat and prevent breakingthe siphon action by admission of air to the short leg.

My device may by obvious changes of form be used when the short leg is circular and maybe used with various forms of siphons including the bent tube form and still be within the spirit and scope of my invention. a p p H The advantages of my apparatus are many. There is a great saving of liquid, ab-

solute certainty of operationand a perfectly wfree liquid and consequently V ficient flushing current;

1. In a device of the character described, a tank ,.a bellsiphon comprising a long leg and a short leg, the open top of the long leg flaring and the closed top ofthe short leg adjacent the open flaring top of the long leg tapering upwardly, a plunger-mounted in said short leg comprising a carrying frame and plates pivotally attached thereto, said frame and plates being adapted to reciprocate in said short leg and said plates to turn on their pivot points, and means for reciprocating said plunger.

2. In a device of the character described, a tank, a bell siphon comprising a long leg and a short leg, a plunger mounted in said short leg comprising a carrying frame and plates pivotally attached thereto having their adjacent ends curved inwardly toembrace the short leg, said" frame and plates i being adapted to reciprocate insaid short leg, and means for reciprocating said plunger. 1

3; In a device'of thechara'cter described,

a tank, a bell siphon comprising a long leg s anda shortleg, a plunger mounted in said short leg comprisinga carrying frame composed of two rings mounted on the long leg of the siphon'and spaced apart and connectedby a bonding link, the upper ring positioned. within the short leg and carry pivotally mounted plates, said frame and plates being adapted to recipro'catein said short leg and the platesto turn on their )ivots and means for red rocatin said plunger. p t

4, In a devlce of the character descrlbed, a tank, a siphon comprising a long leg and a short leg extending down over said long leg, mutually engaging members on the inside of said short legand on the outside of the lon gleg adapted to prevent all movement of the short leg relative to the other except vertical movement and means for starting siphon action.
